Improvement in water-closet valves



UNITED STATES F F ICE.

JOHN BROVER, 0F NEVARK, NEW JERSEY.

Speciiication forming part of Letters Patent No. dv'ium, dated November2Q, 1864.

To all whom it may concern:

Be it known that I, JOHN BROWER, ot' the city of Newark, in the countyof Essex and State ot' New Jersey, have invented certain Improvements inValves for later-Closets; and I do hereby declare the following to be afull and exact description of the sa-me, reference being herein had tothe drawings that accompany this specification and which make part ot'the same.

The nature ot' my improvement consists in rendering the valve seltadjusting and watertight by a peculiar construction ofthe same.

In the drawings, Figure 1 is a view of the under side of the valve andseat. Fig. 2 shows the upper side. Fig. 3 shows the outer edge of thevalve and seat; Fig. Il, the connection of the valve with theclosing-lever; Fig. 5, a sectional view of the valve and seat; Fig. 6,the ordinary way of adjustment now in common use in ships andsteamboats, Fig. 7, the same in section.

lhe same letters refer to the same parts in each figure.

The sectional view, Fig. 5, shows the position of the valve when in use.The'receiving basin is attached to the tiange A on the valveseat B, andits contents are discharged by lifting a handle in the seat, thehandlebeing on the top end of a rod connected to the leverI -usual way (shownin Fig. 7) the edge of the ciieular valve E is beveled, and the seat Bhas the same bevel, the valve E being held to the bar D by the screw andnut .r at the center, and is adjustable by means of the three screwsthat are shown by y in Figs. 6 and '7.

To accommodate the Workman, the valve E has to be removed when thevalve-seat is being connected with the basin and dischargepipe, andthere is no certainty that the adjustment of the valve when replacedshall be correct, and no means, short ot' disconnection, of access tomake needed alterations when the valve is constructed in the ordinarymanner. To obviate this difficulty, I attach the valve to the bar D by aball-and-soeket joint, Fig. el, and have a groove in the valve seat B,

shaped as shown in Fig. 3, and the edge ot' the valve E turned to litthereto. By leaving the nut w a little loose the valve adjusts itselfaccurately when replaced after removal.

It is desirable that the valve should be watertight when closed, toretain water and pre ventodor 5 also, to prevent,the draft of cold airup the water-closets of seagoing and river vessels, which objects areattained by my improvement.

I do not claim, broadly, the adjustment of valves by semisphericalattachments and shaped joints.

What I claim, and desire to secure, is-

A water-closet valve held to its place by a bar secured by asemispherieal connection and rendered Water-tight by means of a V-shaped joint, all substantially as shown and described.

JOHN BROWER.
